Title: Feeder equipment to supply e.g. chips from container to press mould - has storage bin divided vertically into chambers where each material drops out through grids into loader which moves across to mould
Inventor: SCHOLLMAYER VALENTIN
IPC: B29C41/04
Filed: 1992-04-29
Abstract: In equipment for metering particles of chips or fibre material for pressing or moulding, fed out from a storage container into a filler or mould, the container used is divided into a number of feeding chambers, each of which has an outlet with at least one grid. For loading a stationary mould, the example shown has a filling carriage (1) running (A) on tracks (2) and filled from a container overhead (3), so as to fill the mould (4). The container (3) is divided into five vertical supply chambers (5a,5b,5c,5d,5e), each fitted with two grids (6a,6b) at the bottom outlet. Of these one grid (6a) is fixed whilst the other (6b) moves. The area and depth of the chambers (5a-5e) depend upon the size of the mouldings to be produced. When producing pallet skids, the grids of the chambers (5b and 5d) are lower than the others and they (5b,5d) form the ribs, whilst the others (5a,5c,5e) fill the feet areas. Moreover, the relevant chambers (5a,5c,5e) feed finer chips. The complete container (3) is moved vertically (B). ADVANTAGE - The arrangement enables a hopper or a mould to be filled with different materials, e.g., in the prodn. of pallet skids.

Title: Detecting and analysing cell tissue structure in vivo by light polarisation - using laser source, analyser and difference detector in microscope assembly for distinguishing between healthy and pathological tissue for early tumour diagnosis
Inventor: LUDWIG MANFRED DR RER NAT
IPC: G01J4/00
Filed: 1992-05-29
Abstract: A laser (1) delivers polarised light (2) which is rotated to a desired polarisation (4) by a prism set (3.1).

Title: Spinning station on a rotor spinning machine
Inventor: WASSENHOVEN HEINZ-GEORG
IPC: D01H4/32
Filed: 1993-03-26
Abstract: On rotor spinning machines, the sliver draw-in into the opening clothings at the spinning stations is usually carried out by means of drawing-in rollers which are connected via a worm gear to a drive shaft extending along the entire spinning machine. In the event of a thread break, during piecing or when the sliver breaks, the drawing-in roller is separated from the drive shaft via a coupling. The worm gear for driving the drawing-in rollers and the couplings have a complicated and cost-intensive design. It is therefore proposed, according to the invention, that each drawing-in roller (32) together with its drive shaft (41) be connected directly to the drive shaft (42) of an individual drive (39), and that each individual drive (39) be integrated in the cover (3) of the housing (2) of its spinning station (1). <IMAGE>

Title: Process for the production of an air-tight packaging for shelled and boiled eggs
Inventor: WADEN HERMANN
IPC: B65B23/02
Filed: 1993-06-15
Abstract: Food products are increasingly subjected to pretreatment, this pretreatment often not occurring at the place where the actual product is consumed. This is also true of eggs which, for example, are painted with colours for Easter by specialist businesses or for companies in the food sector, such as delicatessens or gastronomic businesses, are delivered hard-boiled and shelled to these businesses. The production process according to the invention is characterised in that there is arranged transversely to the foil-feed direction (arrow) of the packaging structure (7) a further connecting seam (5) which separates a hitherto known chamber into two part-chambers separated from one another in an air-tight manner, and, by the use of a perforating device (12) arranged transversely to the feed direction, a perforation (6) or predetermined tearing line transverse to the feed direction is made in the connecting seam (5). The packaging unit formed by the production process has, for example, ten chambers, each with three eggs, each chamber being separable from the other, with the air seal being maintained. <IMAGE>

Title: Thrust bearing with helix grooves for oil and gas sealing
Inventor: KAYSER ALBRECHT DIPL ING
IPC: F16C33/10
Filed: 1994-03-05
Abstract: Two concentric helix grooves are engraved on a radial bearing face (2), the outer groove (5) extracts oil inwards, the inner groove (4) extracts oil outwards. In between the extracting grooves is a dividing groove (6). The outer grooves end at an axial cylindrical surface (7). An elastomer oil seal (10) is located on that surface carried in a sheet metal cage (12,14) which is either glued or pressed in the shaft (8). The oil in the gearbox separates the oil chamber from the gas chamber using the extracting helix grooves. When the shaft rotates, the lubrication oil is extracted from the area around the elastomer oil seal by the outer helix groove, ensuring no oil can escape into the gas chamber at standstill.
